Tapered Roller Bearings - TDO (Tapered Double Outer) Imperial
Timken® Double-Row Tapered Roller Bearings with Double Outer Race (TDO)
Available in single, double, and multi-row configurations as well as proprietary sizes, these bearings are developed in collaboration with OE engineers to deliver premium performance across various applications. Their power-dense designs support heavier loads and help extend bearing life, while optimized internal geometry reduces torque and operating temperatures to prolong lubrication system life. Additionally, they can be engineered with proprietary enhancements to withstand highly corrosive conditions, high temperatures, vacuum environments, or situations with limited lubrication.
